Clearances For Service & Combustible Materials; Combustion And Ventilation Air; Air For Combustion; Air For Ventilation - PENSOTTI DK2-3 User Manual

This manual is presented in a sequence that allows for an orderly trouble free installation.
We suggest that you follow the instructions in order eliminate potential hazards.
Prior to system installation there should be an inspection of the chimney or proposed vent
system to determine that the condition is acceptable. Repair or replace any defects in the
chimney liner. The vent system and installation must be in compliance with NFPA-211 or
local building codes. Improperly sized vent systems can cause poor burner operation,
sooting, odor or condensation that might create chimney damage. Installation of Barometric
draft controls can insure adequate draft. A minimum draft required at the vent collar is -.01"
W.C.
CLEARANCES
Proper clearances must be maintained not only from combustible materials but also to
provide adequate access for servicing. All installations must comply with local codes and
NFPA-31 and NFPA-211. Consult local fire codes for required clearances. Connections to
chimney must be made with the proper gauge thickness and diameter of fluepipe as required
by NFPA-211.
MINIMUM SERVICE CLEARANCES
Front- 8in. from the front of the oil burner
Back- 18in. from the back of the unit.
Left- 18in. from the side panel of the unit
Right- 1in. from the side panel of the unit
MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS
Front – 18n. from the front of the oil burner
Back – 18in. from the back of the unit
Left – 18in. from the left side panel of the unit.
Right- 1in. from the right side panel of the unit.
Chimney connector- 18in. from the chimney connector.

COMBUSTION AND VENTILATION AIR

Installations taking place in traditional unconfined settings such as basements generally
have an adequate supply of both combustion and ventilation air.
In situations where the boiler is to be located in a confined space with all combustion and
ventilation air coming from within the building two openings must be made with an
adjoining room with one being near the floor and the other being near the ceiling of the
boiler room. These openings must be clear and free of obstacles and measure at least 140
sq. in. per gallon of oil burned per hour.
In instances where the air supply for both combustion and ventilation is to come from
outside the building two air openings, one near the floor and one near the ceiling, measuring
at least 35 sq. in. for each gallon of oil burned per hour.

CAUTION Adequate air supply for both combustion
and ventilation must be available.
